how to compare data

[aratti]

I am glad that finaly your program works as you wanted. Make sure to add the two corrections in red, to your code, otherwise you could experiment some wierd behaviour.

Al.

Include "modedefs.bas"
define osc 4
PORTA = 1
PORTB = 0

KEY VAR BIT [7]
KEY1 VAR BIT [7]
ADR VAR BYTE
COD VAR BYTE
SYMBOL SCLK = PORTB.0
SYMBOL SDAT = PORTB.1
SYMBOL BUZ  = PORTB.2
SYMBOL LED1 = PORTB.4
SYMBOL RELY = PORTB.3
SYMBOL STRT = PORTA.0
SYMBOL UNLCK = PORTA.1
SYMBOL BLCK = PORTA.2

START:
IF STRT = 0 THEN GOSUB SCAN
IF BLCK = 0 THEN GOTO ANGRY 
IF STRT = 1  THEN
HIGH LED1
PAUSE 100
LOW LED1
IF STRT = 0 THEN GOSUB SCAN
IF BLCK = 0 THEN GOTO ANGRY 
PAUSE 100
ENDIF
GOTO START

SCAN:
FOR ADR = 0 TO 7
I2CREAD SDAT,SCLK,$A0,ADR,[KEY]
READ ADR,KEY1
IF KEY != KEY1 THEN ERROR   ' Not GOSUB ERROR
IF (KEY == KEY1) THEN COD = 1
IF RELY = 1 THEN  SEROUT LED1,N2400,["ITS UNLOCKED HERO"]
NEXT ADR
PAUSE 10
RELY = COD 
PAUSE 2000
LOW RELY
RETURN

ANGRY:
SOUND BUZ,[102,75]
HIGH LED1
PAUSE 1000
SLEEP 30
NOP
SOUND BUZ,[102,75]
PAUSE 1000
GOTO START

ERROR:

SOUND BUZ,[102,75]

PAUSE 1000

SLEEP 10 
RETURN     ' Not GOTO START

END
